How to Use the Percentage Calculator
Our tool is divided into three functional tabs to cater to every kind of mathematical query:
1. Simple Percentage (% of a Number)
This method finds an exact percentage chunk of a total amount. For example, if you want to find out what 18% of ₹15,000 is. Just enter "18" in the rate field and "15000" in the total field.
Mathematical Formula: (Total Value × Percentage) / 100
2. Part of Total (Ratio / Grade Percentage)
This tab is useful when you have a specific part value and a total value, and you want to know the percentage it constitutes. It is perfect for calculating test scores or analyzing profit margins. For specific grade-based conversion, you can also check out our Grade to Percentage Calculator.
Mathematical Formula: (Part Value ÷ Total Value) × 100
3. Proportional Valuation (Unitary Method)
The proportional tab resolves reverse calculation problems. Example query: "If my current savings of ₹5,000 equals 25% of my goal, what is my 100% goal?" You would input 5000 as Value, 25 as Old %, and 100 as New %. This is highly beneficial for salary structures or scaling budgets.
